Bad Romance by Lady Gaga is featured in Theatricality, the twentieth episode of Season One. It is sung by Kurt and the New Directions Girls for their theatricality assignment, with solos from Kurt, Mercedes, Quinn, Santana, and Tina.

Vocal Adrenaline dances to it to practice their theatricality and Rachel then proceeds to borrow their idea to help them get ready for Regionals. Kurt and the New Directions Girls are all dressed in Lady Gaga costumes, inspired by actual outfits worn by Gaga in the past.
